The Seagate BarraCuda 120 is a solid-state drive in the 2.5" form factor, launched in 2019. It is available in capacities ranging from 250 GB to 2 TB. This page reports specifications for the 250 GB variant. With the rest of the system, the Seagate BarraCuda 120 interfaces using a SATA 6 Gbps connection. The SSD controller is the PS3112-S12-27 from Phison, a DRAM cache chip is available. Seagate has installed 96-layer TLC NAND flash on the BarraCuda 120, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The BarraCuda 120 is rated for sequential read speeds of up to 560 MB/s and 540 MB/s write; random IO reaches 90K IOPS for read and 90K for writes.
At its launch, the SSD was priced at 61 USD. The warranty length is set to five years, which is an excellent warranty period. Seagate guarantees an endurance rating of 150 TBW, a typical value for consumer SSDs.
